1 Peter 2:1-2 King James Version (KJV)
1 Wherefore laying aside all malice, and all guile, and hypocrisies, and envies,
and all evil speakings,
2 As newborn babes, desire the sincere milk of the word, that ye may grow
thereby:

2 Peter 1:5-11 King James Version (KJV)
5 And beside this, giving all diligence, add to your faith virtue; and to virtue
knowledge;
6 And to knowledge temperance; and to temperance patience; and to patience
godliness;
7 And to godliness brotherly kindness; and to brotherly kindness charity.
8 For if these things be in you, and abound, they make you that ye shall neither
be barren nor unfruitful in the knowledge of our Lord Jesus Christ.
9 But he that lacketh these things is blind, and cannot see afar off, and hath
forgotten that he was purged from his old sins.
10 Wherefore the rather, brethren, give diligence to make your calling and
election sure: for if ye do these things, ye shall never fall:
11 For so an entrance shall be ministered unto you abundantly into the
everlasting kingdom of our Lord and Saviour Jesus Christ.

1 Corinthians 15:58 King James Version (KJV)
58 Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding
in the work of the Lord, forasmuch as ye know that your labour is not in vain in
the Lord.

Acts 2:42 King James Version (KJV)
42 And they continued stedfastly in the apostles' doctrine and fellowship, and
in breaking of bread, and in prayers.
